LJ meme: "Pick Three"

iceraptoress snagged an interesting lj meme that I wanted in on so here it goes:

If anyone else wants to play, comment here and I'll choose three of your interests and three of your icons for you to explain.

She picked from my interests: cordwaining, snarksexual, and therianthropy

And from my pitiful icons (LJ should give free users 10 like JournalFen does):
1. 2. 3.

( Explanations here. )
